"The article deals with monitoring of chemical elements during lifetime of commercially distributed automobile engine oil. The passenger car with petrol engine was used to the observed. Lifetime of automobile engine oil has been stated by car producer in interval 15,000 km. The samples of automobile engine oil have been taken in suitable intervals -- 1,500 km. The spectrometer Spectroil Q100 has been used to monitoring of chemical elements in automobile engine oil. Increase contents of metals and decrease contents of additives were especially observed. The results were modelled using mathematical models with given the values of coefficient correlation R. The models can uses to prediction of condition of engine oil in same or similar petrol engine aggregates." . "9" . . . . "1" . .
